  • 3 models together cover large part of emotion literature Social Sciences: Explain that creating robots is also a way to test the models
  • PEFiC: Perceiving and Experiencing Fictional Characters I-PEFiC: Interactive ADM: Affective Decision Making
  • Print 6 slides in original presentation about this on 1 page
  • Start with Encode / Compare in I-PEFiC ADM
  • Utility ~= Outcome expectancies
  • Emotion regulation strategies broader than Coping (coping focused on down-regulating negative emotions) Coping requires causal connection between coping strategies and emotions they are regulating Gross and I-PEFiC can also control overenthusiasm, maintain positive mood, etc. EMA is more detailed in how emotion regulation works (detailed description in terms of causal interpretation etc.)

    1. 1. Silicon Copp é lia : Similarity and Complementarity Among Three Affect-related Agent Models <ul><ul><li>Matthijs Pontier </li></ul></ul>
    2. 2. Overview of this presentation <ul><li>Short explanation of three affect-related models </li></ul><ul><ul><li>CoMERG Based on Gross </li></ul></ul><ul><ul><li>EMA Based on Smith & Lazarus </li></ul></ul><ul><ul><li>I-PEFiC ADM Based on Frijda </li></ul></ul><ul><li>Comparison of the three models </li></ul><ul><li>Integration of the three models </li></ul><ul><li>Conclusion </li></ul>
    3. 3. Goal of this study <ul><li>Compare three affect-related models </li></ul><ul><ul><li>CoMERG Based on Gross </li></ul></ul><ul><ul><li>EMA Based on Smith & Lazarus </li></ul></ul><ul><ul><li>I-PEFiC ADM Based on Frijda </li></ul></ul><ul><li>Ultimate goal: Create emotional intelligent robots </li></ul>
    4. 4. Gross’ emotion regulation model <ul><li>The experienced level of emotion can be changed by choosing a different: </li></ul><ul><ul><li>Situation Last-minute study vs Dinner </li></ul></ul><ul><ul><li>Sub-situation Talk about exam vs Something else </li></ul></ul><ul><ul><li>Aspect Distract vs Pay attention </li></ul></ul><ul><ul><li>Meaning “ It’s only a test” vs “It’s really important” </li></ul></ul><ul><ul><li>Response Hiding your embarrassment after bad result </li></ul></ul>
    5. 5. Gross’ emotion regulation model
    6. 6. CoMERG in layers <ul><ul><li>Emotion-Response-Level </li></ul></ul><ul><ul><li>Emotional Values V n </li></ul></ul><ul><ul><li>Modification Factors  n </li></ul></ul><ul><ul><li>Personal Tendency  n </li></ul></ul><ul><ul><li>Experiences (e.g. Therapy / Trauma) </li></ul></ul>
    7. 7. EMA Algorithm <ul><li>Construct and maintain a causal interpretation of ongoing world events in terms of beliefs, desires plans and intentions. </li></ul><ul><li>Generate multiple appraisal frames that characterize features of the causal interpretation in terms of appraisal variables. </li></ul><ul><li>Map individual appraisal frames into individual instances of emotion </li></ul><ul><li>Aggregate emotion instances into a current emotional state and overall mood. </li></ul><ul><li>Adopt a coping strategy in response to the current emotional state. </li></ul>
    8. 8. Graphical representation EMA
    9. 9. I-PEFiC ADM
    10. 10. Relations in the model at a glance <ul><li>An Ambition level for a goal is calculated by multiplying Relevance with Valence for that goal </li></ul><ul><li>An Expected utility is calculated for each action, by looking at the Beliefs that goals are facilitated, and the Ambition levels for those goals </li></ul><ul><li>Expected Utilities result in Use Intentions and Action Tendencies </li></ul><ul><li>Action Tendencies for actions increase Involvement and Distance according to action type </li></ul><ul><li>The Expected Satisfaction of an action is calculated by taking a weighed mean of the Involvement-Distance-tradeoff and the Use-Intentions </li></ul><ul><li>The action with the highest Expected Satisfaction is picked </li></ul>
    11. 11. Comparison of the three models
    12. 12. Encoding <ul><li>CoMERG </li></ul><ul><ul><li>Based on aspects. How this happens is left out of consideration </li></ul></ul><ul><li>EMA </li></ul><ul><ul><li>Situations are appraised by utility state predicates and causal interpretation </li></ul></ul><ul><li>I-PEFiC ADM </li></ul><ul><ul><li>Other character is part of a situation, and is encoded in ethics, aesthetics, epistemics and affordances </li></ul></ul>
    13. 13. Compare <ul><li>CoMERG </li></ul><ul><ul><li>Based on cognitive meaning. How this happens is left out of consideration </li></ul></ul><ul><li>EMA </li></ul><ul><ul><li>Compare in terms of Relevance, Utility, Desirability and (other) appraisal variables </li></ul></ul><ul><li>I-PEFiC ADM </li></ul><ul><ul><li>Compare in terms of Relevance, Valence </li></ul></ul><ul><ul><li>Utility ≈ Current Valence </li></ul></ul><ul><ul><li>Desirability ≈ Future Valence </li></ul></ul>
    14. 14. Respond <ul><li>CoMERG </li></ul><ul><ul><li>Emotion response tendencies result in experiential (covert), physiological ((c)overt), and behavioral (overt) response </li></ul></ul><ul><ul><li>Emotion regulation strategies are applied which lead to new emotion response tendencies </li></ul></ul><ul><li>EMA </li></ul><ul><ul><li>Relevance, Utility, and Desirability are mapped to Affective states (covert) </li></ul></ul><ul><ul><li>Affective states lead to Coping behavior (overt) </li></ul></ul><ul><li>I-PEFiC ADM </li></ul><ul><ul><li>Relevance, Utility, Desirability are mapped to Involvement-Distance-Tradeoff / Emotions (covert) </li></ul></ul><ul><ul><li>Involvement, Distance and Use Intentions feed into Affective Decision Making which leads to actions (overt) </li></ul></ul>
    15. 15. Integration of the three models
    16. 16. Conclusion <ul><li>CoMERG, EMA and I-PEFiC ADM were compared </li></ul><ul><li>These three models are based on theories that together provide large coverage of psychological literature in affect-related processes (Gross, Lazarus, Frijda) </li></ul><ul><li>Models are complementary, and therefore we propose to integrate them </li></ul><ul><li>Next step: Implement integrated model in an application in which humans interact with Silicon Copp é lia and perform user studies </li></ul>
